I am running a field trial of Gluster 3.5 on two servers. These
two server use one 10k HDD each with XFS as a brick. On top of
these bricks I have one replica 2 volume: <br>
<br>
[root@nodef01i ~]# gluster volume info ph-fs-0 <br>
<br>
Volume Name: ph-fs-0 <br>
Type: Replicate <br>
Volume ID: 5085e018-7c47-4d4f-8dcb-cd89ec240393 <br>
Status: Started <br>
Number of Bricks: 1 x 2 = 2 <br>
Transport-type: tcp <br>
Bricks: <br>
Brick1: 10.11.100.1:/gfs/s3-sata-10k/brick <br>
Brick2: 10.11.100.2:/gfs/s3-sata-10k/brick <br>
Options Reconfigured: <br>
performance.io-thread-count: 12 <br>
network.ping-timeout: 2 <br>
performance.cache-max-file-size: 0 <br>
performance.flush-behind: on <br>
<br>
Additionally I am running nagios to monitor everything where I
use <a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://exchange.nagios.org/directory/Plugins/System-Metrics/File-System/GlusterFS-checks/details">http://exchange.nagios.org/directory/Plugins/System-Metrics/File-System/GlusterFS-checks/details</a>.
I improved it slightly such that I monitor number of split-brain
files and all this information go to the performance data,
therefore I can draw pictures out of it (these pictures are in
attachement). <br>
<br>
My problem is that I am receiving quite a lot of false warning
from nagios during a day because there are some unsync files
(gluster volume heal XXX info). I dont know if it is a bug or it
is cause by my configuration. Either way it is quite disturbing
and I am afraid that after receiving a lot false warning I could
just omit an important one.. <br>

I think the issue is because the "gluster volume heal info" also
reports files undergoing I/O in addition to files that need
self-heal. see <a moz-do-not-send="true"

for more information on this. Pranith, please correct me if wrong.<br>

That's what I've seen as well.<br>

another note, we are also developing Nagios plugins that can be

network.ping-timeout is set to 2, because I can not allow VM
servers to hang for 2x42sec when other node is rebooted (we have
some kind of reboot policy).. <br>
<br>
Thanks for help, <br>
